Answer:
56x + 34
Step-by-step explanation:
12(3 + 5x) + 1/4(16x - 8)
First, use the distributive property. You will get:
(12)(3) + (12)(5x) + (1/4)(16x) - (1/4)(8)
Next, multiply the numbers. You will then have:
36 + 60x + 4x - 2
Now, rearrange the numbers. The variables go in the front. This is what it should look like:
60x + 4x + 36 - 2
Add 60x and 4x, then subtract 36 and 2. This is your answer:
56x + 34
Answer:
You should select at least 216 statistics professors.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
You should select at least 216 statistics teachers.
Answer:
5 < x
Step-by-step explanation:
first, we want to isolate x, so to get rid of the denominator of 2, we can multiply both sides by 2 to cancel it out
3(2) < 2(x/2) +1
6 < x + 1
now we subtract one from each side
6-1 < x +1 -1
5 < x
hope this helps!
Answer:
The states of nature refer to future events, not under the control of the decision maker, which may occur. States of nature should be defined so that they are mutually exclusive and collectively exhaustive.
Answer:
Joe makes 5 dollars a week
